ThO

Tho is a term that can function as a personal name, a surname in some contexts, or an acronym, depending on language and setting. Its meaning and usage vary across cultures and fields, so the interpretation of Tho relies on the surrounding context.

In Vietnamese, Thọ (often rendered without diacritics as Tho) is a given-name element meaning longevity or long life. It is commonly used in compound given names and may appear by itself in Vietnamese naming practices. When written in non-accented form, Vietnamese characters like Thọ are typically transliterated as Tho, which can appear in English-language records, signage, or diaspora communities.

Outside Vietnam, Tho may occur as a personal name or a shortened form of longer names in some communities or transliteration schemes. It is comparatively less common as a surname but can arise through transcription variations or name changes in multicultural contexts. In English-language sources, Tho may appear as a first name or, less frequently, as a surname, depending on individual family naming choices.

In uppercase form, THO functions as an acronym or code in various domains, with meanings that are specific to a particular organization, field, or document. Because there is no single universal definition, THO should be interpreted from the context in which it appears.
